Newbies say hello / Re: Hello and workshop manual for 1970 Falcone (Nuovo)

Thanks Rob for all that info. I'm not sure if my mechanical skills are up to some of the things you recommend but I'll ask around for help. Appreciate the suggestions. Should I be concerned about the valves with modern unleaded petrol? Cheers John

It's quite easy to translate the online manuals & parts books from Italian to English, using Google translate.  After a while you get used to certain words anyway.

Alternatively you can get an English workshop manual from Martin Noke.  Have a look on Ebay.  They cost GBP 20.00 and are very worthwhile having.

https://www.ebay.co.uk/itm/203756290354?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338268676&toolid=10044&customid=CjwKCAiA6Y2QBhAtEiwAGHybPbL2Rt_yKNM6qp5cAvhU_pkHHL1UJponAlotcjm2YB81BRGsGW0o1xoCYiQQAvD_BwE

Useful mods are to add an extra oil feed to the top of the engine to help lube the inlet valve.  You should change the engine & fork oil seals as almost all rubber parts will have perished by now.  Be very careful with the fork top nuts as they are aluminium and the threads strip easily, especially as you will reinsert them against the spring pressure.

Change the headlight out for one from a Mk1 VW Polo (if you had them in Oz).  It's about the same size but will enable you to have an H4 halogen headlight, but not exact. The headlight glass will rest directly onto the headlight rim, but you can put rubber U channel onto the rim to protect the glass. You will need to fit relays to control the high & low beam so you don't overload the handlebar switch.  Useful to have a relay on the horn too.

If you need to remove the flywheel, you can't get the original castellated socket for the special nut inside the flywheel.  However there is a Honda suspension tool that will do the job.  The thread is the opposite to normal and you might need a rattle gun.

Clutches can slip mainly due to age & old oil.  Oddly, this can happen at high cruising speeds. Replacements are available, but expensive.  Use new heavy duty springs.  Not a difficult job to do (can be done with the engine in the frame) but you will need to make a clutch compressor (easy).  Once done, I suggest you use oil developed especially for wet clutches (for peace of mind). Then you can forget about the clutch.

You could also fit a Dynastart instead of the dynamo.  It takes a bit if engineering, but saves kickstarting the bike. 

New petrol taps are rubbish.  The NF has a peculiar M12 thread, not common to other types.  If you get new taps, the seals are easy enough to replace, but have a tendency to move inside the tap housing which can restrict fuel flow.

Otherwise, it's an interesting bike to ride and will turn heads.

Hi. I've just acquired a 1970 Falcone Nuovo. It's one of a group that was discovered here in Australia that was formerly property of the Yugoslav army. I'm primarily interested in getting an English translation of the workshop manual and hooking up with other Falcone owners here in Australia. Anyway I appreciate the existence of this group, despite a downturn in traffic. Cheers John

Links / NF Article in Real Classics Magazine

Hi All,
and Happy New Year
The January 2022 edition of 'Real Classics'  magazine has an article about owning a Nuovo Falcone.
Written by a regular contributor, who has a collection of interesting and thoroughbred bikes, it is quite complimentary.
Mentions the 'downs' without moaning and praises the good points.
i enjoyed it, a recommended read.
(Includes some excellent photos as well).
Cheers,   Phil

Engine and Transmission / The new clutch test run
« Last post by Rob vW on September 20, 2021, 04:46:42 pm »
On Sunday I did somewhere around 140-150 miles on the road trial.  That was at least a 30 mile round trip to get to the start/finish, plus 90 miles for the 2 road trials, plus some for getting lost!

The weather was variable throughout the day, being damp in the morning and sunny in the afternoon.  The roads varied from reasonable B roads to unmade dirt tracks.

All in all, the NF went really well, but most importantly, the clutch did not slip once.  I had one moment where I stalled the bike as I was in gear and couldn't adjust my grip on the clutch lever.  It was just a touch heavy at that moment.  But during the rest of the day it wasn't a problem.

Therefore I can declare the clutch cured.

Sorry to hear that Rob, but don’t let one bad apple spoil what has become quite a useful resource. For what it’s worth, getting my wheels rebuilt in stainless back in 2003 was the best money I ever spent. My Polizia model also has a leak, but so far I haven’t managed to get the flywheel nuts off. I’ll be several hundred miles North of you in the Cairngorms, but hope your day goes well. Come up to the Scottish double some year. It was a great pair of weekend runs pre-Covid!

I suspect that the oil leak is coming from the neutral switch or from the drive seal.  You can see the leak area just ahead of the kickstart quadrant.

As a precaution I have ordered new seals for the flywheel shaft and gearbox/sprocket drive.  They are double lipped and in viton.  Expensive, but worth it.  I have a similar problem on my BMW airhead where the new seal behind the alternator is leaking.  That will definitely be replaced with a double lip viton seal.

I don't bother with the facebook page for the NF now, not since an a**hole in the USA tried to tell me (the way it was written was in the vein of "thou shalt not!" (do all Americans write this way?)) I was wrong to use stainless steel wheel rims and must never use stainless wheel steel rims.  I don't mind friendly advice & friendly suggestions (my advice/experience) is offered in the same way, but when some complete idiot tries to order me not do what I want with my own bike, it's time to leave.

Anyway, if anyone is in the vicinity of the Old Crown pub at Snarestone, Leicestershire, on Sunday 19th, the Taverners section of the VMCC are holding their Road Trial, and for the first time ever, I am having a go and riding the mighty Nuovo Falcone, complete with stainless steel rims and spokes and slight oil leak.

Wish me luck and give me a wave if you see me.  I am on a blue ex-Carabinieri bike.

Bummer about the oil leak Rob (where from?).
Still, it’s good to hear you now have a clutch that works…  8)

With regard to the new clutch, I cannot now be sure if it is the new springs, or friction plates or change of oil type that has cured the clutch slip. 

According to Uwe Pirner, the clutch was marginal from the start (his words, not mine).  Obviously, someone has had the engine apart at some time on my particular machine as the springs I removed were 45mm long compared with 35mm as standard.

The clutch friction plates I removed were pretty much unworn.  They were the same thickness as the new friction plates.  However, the material might have been contaminated with the incorrect oil.

Of course, I have no idea what oil was used originally.  I had used a 20W50 mineral oil.  However, this time I have used a 20W50 mineral oil which is JASO rated for wet clutches.

I had a slipping clutch.  Now I don't.

However, I do have an oil leak! :-(

Thanks for the three write-ups on this Rob, and sorry for the long delay in replying.
I'll be honest ad say that after checking the site dozens of times and finding nothing new, I just gave up!
You're lucky to have someone to ship for you.
So many parts are available only from Germany, and so few suppliers seem at all interested in the hassle of dealing with the UK, and who can blame them if they have plenty other customers.
I bought a set of used plates off eBay, and hope they will see me through if I do run into problems,
